Once the correct connections have been made for the selected test type, press the Start button. The RCD
will be powered and you will be prompted to reset the RCD. When you have reset the RCD the PrimeTest
will count down and then perform the RCD test, the RCD trip time will be displayed. The measurement will
be displayed in milli seconds.
13.6 IEC Lead / Polarity
The Polarity test checks the wiring polarity of an IEC lead, the IEC should be
plugged into both the Equipment Under Test (EUT) socket and IEC test
sockets on the PrimeTest.
This test can be used to test the wiring polarity of extension leads by plugging the supplied test IEC lead into
the end of the extension lead to complete the circuit to the IEC tests socket.
In the Automatic sequence editor the Polarity can be added to sequence. In the Manual Mode the polarity
test is already part of a pre-defined test sequence which includes an Earth Continuity test, Insulation
resistance and the Polarity test.
13.7 Substitute (Alternative) Leakage
This test is applicable to Class I and Class II equipment and it is used to verify that the Leakage between the
mains conductors of the Equipment Under Test (EUT) to the EUT earth pin, or conductive accessible
surface of the enclosure, is to a satisfactory low level.
There are two possible connection methods for the Substitute (Alternative) Leakage test.
CLI and IEC Substitute (Alternative) Leakage
The test is performed between the EUT test socket live and neutral and the EUT
socket earth pin.
For IEC leads the other end of the lead should be connected into the IEC test
socket.
